Notes: Here's the color version of the image that was taken on Christmas night (see Ha black and white image below). This is lower resolution than I'd like because of the 2x2 binning and the moon being out but the colors did turn out better than I expected.

I used Ken Crawford's tutorial on combing Ha, OIII and SII filtered images using levels and cliping masks.

Click image for full size.

The second image was created using Peter's Photoshop Actions. I just took the top image and used the new action step 'Increase Dynamic Range'. That's all. I think it improved the image quite a bit. Clicking on the two images for full size will show the difference better.

Horsehead and Flame Nebula

click here
©2007 Richard Murray

Notes: I started imaging this on Christmas night. Clear nights have been so rare lately I have to go out whenever the skies open up. This was taken on a very bright night with the sixteen day old moon very high in the night sky. Only use of a narrowband filter could result in any kind of useful image so I used an Ha 6nm filter for the above image.

I also got some OIII and SII filtered images so in a few days I'll show the color version which should be fairly colorful despite that pesky moon.

Comet 17P/Holmes Bicolor Narrowband


©2007 Richard Murray

Notes: This is a first light image from my new observatory and is a bicolor image using Ha and OIII narrowband filters with a synthetic green channel. This isn't the natural color of the comet but it does bring out more detail of its inner structure.

The bottom image is a color negative of the above image.

When Comet 17P/Holmes exploded back in October of this year it shed about 1 percent of it's mass which is the equivalent to the Earth losing its entire crust! At this point the comet is actually larger in the sky than the full moon.

Just One Clear Night


©2007 Richard Murray

Notes: It's a well known fact in the amateur astronomy community that if you buy a new astronomy gadget you can suffer for days or weeks (depending on the gadget) with cloudy weather. It's been cloudy for three weeks now since I had my new observatory built so I figure I have about a week to go before clear skies. :>))

Since I don't have anything else to take pictures of, above is the latest picture of my observatory through my den window.

Getting Closer to First Light



The Captain and I are almost ready for our first voyage, er ah, I mean first light. I almost thought I heard him say "Take her out Sulu. :>))

Notes: We have electric power now. Notice the futuristic gym flooring and the nifty red rope lights. Also the warm room curtains are up. The advantage of installing gym flooring is it's made out of rubber, so if you drop some equipment it doesn't break; it just bounces.

Notes: This was a short exposure run just to test out the GRAS3 scope in New Mexico (1 of 6 scopes available for rental at that location).

The good news is the Tak 150 has about the same field of view as my 80mm Megrez APO which means I can combine images taken at my home observatory with those taken with the Tak in New Mexixo. :>))

Techno Stuff: 10/6/07 Camera: SBIG STL-11000M , Imaging Scope:TAK FSQ-106 ED, One 60 sec exposure with a clear filter, Autoguided, Processed with CCDStack, Photoshop CS2, PixInsight

Notes: I'd like to say I went out and bought a bunch of new insanely expensive equipment but I didn't. This is my first image taken using equipment that is part of the Gobal-Rent-A-Scope stable of fine instruments which are located throughout the world.

This image was taken by me over the internet with a robotically controled scope located in the central part of South Australia on 10/6/07 at 3:30am Ausie time. Here in the US at my location it was in the early afternoon.

Keep in mind this is not a stack of exposures. It is just one 60 sec exposure through a clear filter when the moon was at 33% illumination. Not bad at all for such a short time.

The Beginning Of My New Observatory

The hole is dug for the pier.

Notes: This is an Ha:sG:OIII narrowband image with Ha mapped as red, OIII as blue and a synthetic green generated from the Ha and OIII images. I took this back on June 20th but didn't have a chance to process it until now.

I didn't plan on the colors turning out this way but I think the black and orange are appropriate with Halloween just around the corner. :>))

In the two images below the colors are remapped to red:green:blue respectively.

Notes: This is a Ha-LLRGB image which shows the red H-alpha regions surrounding M31. Lots of processing on this image as integrating Ha data with LLRGB is more complicated than I thought. Just for fun, I've also included a widescreen version for those with widescreen monitors.

Notes: This is an LLRGB image using a synthetic green channel. It was taken under murky conditions with high altitude clouds forcing me to keep the exposure time down. The RGB color required a heavy saturation boost plus LLRGB layering in order to realize much color at all.

Techno Stuff: 8/18/07 Camera: ATK-16hr, Imaging Scope: Megrez 80mm APO at F/6, mounted on LX90 8" SCT, Ha 6nm, 76 minutes total with two 30 min subs and one 16 min sub (interupted due to clouds), binning 1x1, Autoguided with DSI Pro and PHDGuide from LX90, No Darks, Processed with CCDStack, Photoshop CS2 and PixInsight

Notes: Seldom imaged by amateur astronomers, this is a very faint emission nebula in the constellation Cygnus. This is located due east of the popular Crescent Nebula. Sh-104 is viewed by professional astronomers as a good illustration of the "collect and collapse" model of star formation triggered by the rapid expansion of a Helium II region.

Techno Stuff: 5/18/07 for Luminance and RG and 8/11/07 for B, Camera: ATK-16hr, Imaging Scope: Megrez 80mm APO at F/6, mounted on LX90 8" SCT, Luminance IR 11 minutes total with 1 min subs and 80 minutes total with 5 minute subs binning 1x1, Red and Green 20 minutes with 5 minute subs binning 2x2, Blue 30 minutes with 6 min subs binning 2x2, Autoguided with DSI Pro and PHDGuide from LX90, Darks Applied Luminance Only, Processed with CCDStack, Photoshop CS2 and PixInsight.

Notes: I imaged the luminance, red and green frames in May but it took me until August to get some decent blue frames. The full size image is small because the blue frames had to be rotated almost 45 degrees to match up with the earlier images. But it all turned out ok in the end.

The second image is the same as the first but processed by combining the red and blue frame with a synthetic green frame along with the original luminance frame. Once this was processed in Photoshop, the top image was desaturated (color removed) and this was placed on top as another luminance frame to create what is called an LLRGB image.

Notes: The color image had to be cropped due to rotation of the RGB images which were taken on the following night. This was much easier to process in grayscale than in color. The color image took two separate processing attempts and I settled on the second try.

Techno Stuff: 7/29/07 ATK-16hr, Megrez 80mm APO at F/6, mounted on LX90 8" SCT, Halpha 6nm 160 minutes total with 20 min subs no binning, Autoguided with Atk-2hs and Guidedog from LX90, No Darks, Processed with CCDStack Photoshop CS2 PixInsight

Notes: Just as most emission nebula in the Milky way emit prodigious amounts of energy in the Halpha range, there is no reason why emisson nebula in the Andromeda Galaxy shouldn't as well. So I spent the night imaging M31 using an Halpha filter to see if I could find a few. And there they are, sprinkled throughout the sprial arms.

The one which I've highlighted is a dead ringer for NGC2359 Thor's Helmet. Imagine an alien amatuer astronomer imaging such a giant emission nebula as this! (I sure would like to know what kind of astronomy equipment he, she, it is using) :>))

Notes: Let's just say this was a real adventure in color processing. I can't recall imaging an object that had this many colors pop out at once during processing. But that's part of the fun of doing what I do.

Looks like there is a very clear light bridge from M31 to it's captured satellite galaxy M32.

This image was taken on a very special night. Even though several neighbors had there porch lights on, the night was crystal clear with the milkyway in full view.

Notes: To get all the details of M106's core please look at the full size image. I did the best I could on the color. I started out with the whole thing looking yellowish green so I switched to Lab Color in Photoshop and the color processing went a lot smoother.

The large galaxy is M106 and the edge on smaller galaxy right next to it on the left is NGC4248. The two galaxies next to that are NGC4231 and NGC4232. There appears to be a faint light bridge between them so they may be interacting. The larger edge on galaxy at bottom right is NGC4217 and to the right of it is NGC4226. I'm pretty sure the faint galaxy just below M106 is UGC7356.

Notes: My original plan was to just try out my new Q-Guide autoguider (cmos webcam) and PHDGuide expecting a night of frustration while I worked the bugs out. Even if it was the unlucky mornning of Friday the 13th, after a few hiccups the darn thing started to work, so I went over to the constellation Cepheus and got this image. Notice the large Calf Head in the upper center (Keep looking, you'll see it. Hint - It's turned sideways with the nose pointing right).

This is part of a much larger nebula, much too large for my setup, but I managed to also image another portion near the bottom of the complex which I'll post next after the processing is done.

Notes: The IR (Infared/UV blocking filter) frames turned out very well. However, the RGB (red, green, blue filtered) frames suffered from heavy light pollution gradients which CCDStack took care of surprisingly well allowing me to come up with a decent final image. I like doing LRGB processing and plan on doing more with fairly bright objects like M104.

Notes: There was every reason in the world why this image should not have come to be. The night was murky and foggy, the object was at a low altitude (33 degrees), I forgot to plug in my dew strap so each exposure taken left the Megrez objective more and more fogged up. So frankly, I think I deserve a little applause for ending up with a halfway decent image. :>D

Notes: This is a cluster of galaxies from Paul Hickson's Catalog of Compact Galaxy Groups. I've counted seven galaxies so far and will be putting up a labeled chart later. There's a substancial green halo around the large yellow star which you can see in the full sized image. I don't know if this is real or an artifact caused by optics.
